How do I prototype this?

[Kevin D. Quitt]

    I'm invoking functions through an array of struct.  My compiler generates
a warning in the following two cases.  How do I declare prototypes given:


---------------- Example 1

-------** in the .h file:

struct  token_def
   {
    u16     index;
    u16     match;                      /* # of chars to match, 0 = all     */
    u8      name[16];
    i16     (*fn)();                    /* Function to call                 */
   };


-------** in the configuration file:

struct token_def    configuration[] =
   {
       { TITLES,    0, "TITLES",    paint_titles        },
       { REPAINT,   0, "REPAINT",   collect_repaints    },
       { PBLOCK,    7, "PBLOCK_",   define_pblock       },
       { TBLOCK,    7, "TBLOCK_",   define_tblock       },
       { UPPER,     0, "UPPER",     define_upper_platen },
       { LOWER,     0, "LOWER",     define_lower_platen },
       { TOOL,      0, "TOOL",      define_tool_probes  }
   };


-------** in the code file:

extern struct token_def configuration[];


----** then, this:

        (*configuration[ tnum ].fn)( cfg, token );

----** gets:

pm.c(330) : warning C4071: 'configuration' : no function prototype given


----------------------------------------------------------------
#2

struct  parse_info
   {
    CMD_IN  *pici;                      /* Ptr to command input struct      */
    u16      piexcl;                    /* Boolean - exclusive command list */
    u8      *piparam;                   /* Ptr to parameter string          */
    u16      piplen;                    /* Length of parameter(s)           */
   };

#define MAX_PARSE_DEPTH (16)


local struct parse_info pi[ MAX_PARSE_DEPTH ];


----** this:

    (*(pi[0].pici->func))();

----** gets:
input.c(762) : warning C4071: 'function through ptr' : no function prototype given


    Note also that depending upon the circumstances, the call will have
zero, one or two parameters.
